I have a 2003 model crf 450.....due to the economy , it has a disappointing resale value. If you were to run this on the street ...what sort of gas mileage would it get??? I would just use it for short trips ( 15 miles one way) . I have had it since 02 , and hate to give it away. But either need it out of the garage , or need to start using it again....my primary racer is a 250 rm...and want to keep it that way. I like the yamaha wr/x250 but can't sell something for cheap and buy something for full retail. Can anyone lead me to any websites for dual sport kits ??? Thanks.
